I'm not a pro... just a passionate amateur, so I don't want to spend the money really professional gear would cost.
Do any of you have recommendations for something reasonably good? Is the best idea a wireless lapel mic? Would the receiver be connected to one of the cameras, or is the audio recorded separately and then added later?
I saw this on the B&H website, and I hope I won't have to spend quite that much but I could be convinced to if you all think it's good: http://www.bhphotovideo.com/c/product/999979-REG/polsen_cam_2w_g1_2_channel_vhf_camera_mount.html
Thanks for any suggestions.
